I use the all metal ones and they are difficult to remove when burred up, but easier than the plastic ones. One tip...to clean them put them in a solar wax melter for a day (a very warm or hot day) and they will come out clean as a whistle. No scraping.
I just bought a wood-bound one and can see how they would be the best choice, though the most expensive. ($12 vs. $5 for metal, $3 for plastic)
